LAMP.

To all 'whom 'it may concern;

Beit known that L VVILLIAM C. COLEMAN,

a. citizen of the United States, residing at Wichita, in the county of Sedgwick and 5 State of Kansas, have invented certainnew and useful Improvements 1n Lamps, of'

which the following is a specification.

The present invention relates more particularly to lamps of the type, in which a hyvapor, which in turn is mixed with vair and conveyed to illuminating means, preferably of the mantle or incandescing type.

The primary object is to provide `a novel, simple and compact structure, wherein the essential parts may be'readily removed and v cleaned, the light easily" regulated, and a very high degree of efliciency obtained Two embodiments of the invention. are

disclosed in 'the jaccompanying drawings,

wherein Figure 1 is a side elevation of one form of construction with the globe and'fgllobe support illustrated 'in section. ,'Fig.' 2isa vertical sectional Viewf therethroughLfFig.y 3 is a horizontale-sectional'viewfon the line 3 3 of Fig. 2. Fig. 4 is a -viewin eleva-I tion of a slightly modiiedform of' construetion, taken at right 'angles to Fig. 1. Figi 5 is a detail sectional view on the line `5 5 of Fig.4. Y

Similar reference numerals designate corresponding parts in all the figures of the drawings.

In the embodiment disclosed in Figs. 1-3 inclusive, a mixing chamber 6 is employed that also constitutes the canopy of the lamp. This mixing chamber is provided with a central passageway 7, in which islocated a central vertical vaporizing tube 8 that eX- tends downwardly below the mixing chamber, and is provided with an elbow 9 connected .to a valve casing 10. Projecting upwardly from this valve casing, at one side of the tube 8, is a vapor-discharge nozzle 11. It will be observed that the valve seat 12 of I the casing is interposed between the tube 8 and the nozzle 11', and a combined vapor cut-ofi' and regulating valve 13, loca-ted in 12, for the purpose of controlling the supply of vapor to the nozzle.

The nozzle 11 projects upwardly into the lower end of a combined vapor and airconducting tube 14, the upper end of which is connected to and communicates with the drocarbon or other fluid is rst changed into and into the nozzle 11.

interior of the chamber 6. The lower end of this tube has an offset air intake 15 disposed at substantially right angles to the nozzle 11. Extending downwardly from f the mixing chamber 6 on the opposite side of the vaporizing tube 8 to the pipe 14, is a fuel-conducting pipe 16, the lower end of which is offset, as shown at 17, so that it is 'in axial alinement with the vaporizing tube '8. This depending end is provided with a suitable mantle support 18. Y

The operation of the structure is substantially as follows. The fuel to be vaporized, is vconducted to the upper end of the tube 8,

vand passing down the same, is converted into vaporwhich flows through the valve casing It is expelledup- 'wardly from said nozzle through the pipe 14 Vand the air entrained with it, is carried into vthe mixing chamber` 6. From thismixinw chamber, the vaporized orv gaseous fue "passes down the pipe 16 to the mantle. In-

this structure, it isto be observed that a straight vertical vaporizino' tube '8 is em- 'ployed that may be readilyl removed' and` cleaned.' Furthermore the nozzle is entirely accessible, for the purpose of cleaning, and inasmuch as this nozzle projects upwardly,

"there is comparatively vlittle danger of its becoming clogged from sediment accumulat-` ingntherein;y The particular arrangement and construction of the valve is important. It is to be observed that this is not a needle valve, in the strict sense of the term, but a cut-oftI and regulating valve that is interA .posed between the vaporizing tube and the 'nozzle so that the amount of vapor delivered Yfrom the nozzle may befe'asily controlled and 'the' light raised and lowered, as desired.

A slight modification of the structure is disclosed in Figs. `4 and 5. In this embodiment of the invention, a vertical vaporizing tube 19is employedl that passes downwardly through a channel 20 formed in the mixing chamber21. This mixing chamber is substantially-U-shaped in cross section, as shown in Fig. 5. The combined air and vapor conducting tube 22 is` ranged in rear of the vaporizing tube 19, dhd two depending tubes 23 conduct `the gaseous mixture downwardly to the'mantles 24 suspended therefrom. The arrangement other than that described is the Asame as already set forth, and it will be obvious that one or more mantles may be employed as desired.

From the foregoing, itis thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art, without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of constructionlmay'be resorted to, without departing from the spirit or sacrificing any of the advantages of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

l. In a vapor lamp, the combination with a vertical vaporizing tube, of an air mixing chamber located at the upper end thereof, a vertical combined air and vapor conducting pipe depending from the mixing chamber at one side of the vaporizing tube, another pipe also depending from the air mixing chamber and disposed alongside the vaporizing tube, a mantle support carried by the lower end of the latter pipe, an upstanding nozzle connected to the .lower end` of the vaporizing tube and delivering into the combined air and vapor conducting pipe, and a combined cut-ofi' and regulating valve controlling the passage of vapor through the nozzle.l

- 2. In -a..vapor lamp, the combmatlon with a vertical vaporizing tube, of a mixing chamy ber located at its upper end, a combined air and vapor conducting pipe located along-pV side the vaporizing tube and communicating at, its upper end with the chamber, a nozzle for delivering vapor from the lower end of the vaporizing tube into the conducting pipe, a vapor burner connectedl to the mixing chamber and disposed adjacent to the nozzle, and a transversely disposed combined cut oil' and regulating valve for controlling the Vpassage of -vapor through the nozzle, said j valve having an actuating handle disposed out of the range of heat from the burner.
